Regex Pattern Ignoring Something It SHOULD Pick Up (Though I may be wrong...)
|
Ok, here is the text I'm working on (I know Rift regexes have been visited MANY times)
| Code: |
Glancing into the Rift, you see:
[ 489] bayberry bark [ 419] bellwort flower [ 523] black cohosh
[ 236] bloodroot leaf [ 2] blue ink [ 5] blueberry
[ 10] cloth [ 22] eagle's feather [ 361] echinacea
[ 579] ginger root [ 81] ginseng root [ 256] goldenseal root
[ 340] hawthorn berry [ 139] irid moss [ 219] kelp
[ 457] kola nut [ 207] kuzu root [ 267] lady's slipper
[ 350] lobelia seed [ 295] myrrh gum [ 438] prickly ash bark
Type MORE to continue reading. (66% shown)
more
2261h, 2318m, 10184e, 12590w exdb-
[ 266] prickly pear [ 4] red ink [ 22] rope
[ 12] sidewinder skin [ 130] sileris [ 364] skullcap
[ 284] slippery elm [ 267] valerian [ 34] venom sac
[ 6] weed [ 93] wood
2261h, 2318m, 10184e, 12590w exdb- |
Now, I'm using this regex to capture the lines, but it is ignoring sileris and valerian. And I cannot explain why. So, any help is appreciated.
| Code: |
| ^\s*\[\s*(\d+)\] ([\w' ]+)\s*(?:\[\s*(\d+)\] ([\w' ]+)\s*)?(?:\[\s*(\d+)\] ([\w' ]+)\s*)? |

Here is what I see (I'm #ECHO'ing anything the trigger detects for testing purposes)

As you can see, it matched everything, using the same trigger pattern you are *shrug* Check all your triggers and make sure you don't have one that counters this one would be the only suggestion I have at this point.

EDIT: I changed something in the value of the trigger to see if I can match it to your output, and I succeeded, oddly enough. Here's a second output of the same test:

As you can see, it missed parameter 4 completely on two of the last three lines and parameter 2 on the last line... It even missed cloth on one of the other lines, too. Weird. I'll see what I can come up with. |

| Code: |
| ^ \[\s{0,3}(\d+)\] ((?:[\w']+ ??){1,4})\s*+(?:\[\s{0,3}(\d+)\] ((?:[\w']+ ??){1,4})\s*+(?:\[\s{0,3}(\d+)\] ((?:[\w']+ ??){1,4})\s*+)?)? |
The first space is always a single space there is no reason to use an * on it.
The spaces between the [ and \d can only be in the range of 0,3; backtracking is reduced by actually expressing it that way. The acceleration is likely extremely small, but considering the number of \s* in the pattern it makes good sense.
There has to be 2 entries on a line before there can be 3, so nest the optional parts.
"[\w' ]+" would want to pick up all the spaces with the words until the next "[" the \s* shouldn't have aproblem with it, but it can cause confusion to the regex engine. I reexpressed that as "(?:[\w']+ ){1,4}", then examined the need for \s* to still follow. Finding it need to be there the "??" was added to the space to make it self trimming and place the preference for the space to not be matched with the words. At the same time I added possesiveness to the \s so it would try to grab away that trailing space. |

Vij, using it with the \* for offline testing (spaces don't always echo when I enter lines on the comman line) But other than that I don't see why my regex didn't work. Might not have been the most efficient, but whenever I put in one of the lines that has something on it being ignored into the Test box it properly reads the line. So I'm not sure what else is wrong. I'll try your pattern anyways and see if it helps.
